[Prior Art] In recent years, the touch screen has gained market recognition due to the adoption of touch phones. Therefore, many manufacturers have joined the development and design of touch screens. Among them, the capacitive touch control device is a next-generation product that can replace the current mainstream resistive touch screen due to its good tolerance and better touch experience. However, due to the relatively high cost of capacitive touch devices, it has become the main reason why it has not been widely used in consumer products. Many electronic products, such as mobile phones, cameras, PDAs, and laptops, in order to be in a limited volume, the visual display of the 帛 帛 以及 以及 and the more convenient operation mode 'part of the electronic products will __ plate touch group Combine to form a touch device. In addition, in order to avoid scratching or staining of the surface of the touch device, the touch device is usually mounted.
